Well, testing camera drivers without userspace support is not really
possible. Yes, you can use mplayer to display the data in "preview"
mode, and yavta to adjust focus/exposure... But that's really
hard/slow and preview quality does not tell you much about quality of
final photo.

So... yes, I'd like to see this in.

Best regards,
